- Add ruby 1.9 support
- Implement new knobs for gems and rake (these are included in
  ruby 1.9 distribution already). Also move gem bits from
  ruby-gems/Makefile.common to bsd.ruby.mk[1]. Now to depend
  on gems or rake you should define USE_RUBYGEMS/USE_RAKE
  accordingly. Also RAKE_BIN variable is provided for
  pointing to the right rake executable.
- Rewrite RUBY_SCHEBANG in awk to eliminate build dependency
  on ruby.

EventMachine implements a fast, single-threaded engine for arbitrary network
communications. It's extremely easy to use in Ruby. EventMachine wraps all
interactions with IP sockets, allowing programs to concentrate on the
implementation of network protocols. It can be used to create both network
servers and clients. To create a server or client, a Ruby program only needs
to specify the IP address and port, and provide a Module that implements the
communications protocol. Implementations of several standard network protocols
are provided with the package, primarily to serve as examples. The real goal
of EventMachine is to enable programs to easily interface with other programs
using TCP/IP, especially if custom protocols are required.
